I'm avoiding using any golden hammers. So far, I have 4 challenges left, and haven't used a hammer yet. I have boss battles on intense, 100 man brawl with all characters, collect all stickers, and get 2000 kos. the stickers and 2000 kos I will eventually get through playing the game. 100 man brawl, it's just spamming one strong move that prevents the opponents from attacking you. So far, I think I beat it with 5, but I haven't been playing it much. It doesn't look hard, just extremely time consuming.
As for intense boss battles, I seem to always get through 6 before I die. I've tried with game & watch, yoshi, fox (lazer spam), kirby, and ike (super armor with up-b), and none of these have done extremely well for me. The one character that I seem to do the best with is... JIGGLYPUFF??? I can float inside them or just behind them so that they won't be able to hit me with most of their attacks. I actually managed to kill 6 of them with jigglypuff without even taking damage!!! But died at the next boss
. I know I can beat it, but it will just take a while...
As for those who say beating all-star on intense is impossible, if you have 9999 coins, you get over 100 restarts (as you gain coins with each batle). So it's not impossible. If you have problems with your main, try different characters, and you will find one that can beat them easily (like I did with boss battles and jigglypuff). I beat all-star intense with about 10 restarts with game & watch.
Well, I'm going to try to finish all the challenges without using hammers. Then I can say I beat all the challenges. Using hammers, you haven't beaten them all, but you have completed the challenges mode. Well, that's my opinion. Not everyone agrees with this. So if you disagree with my ideas, I don't mind if you post and disagree. But lets not turn this into a war thread
